How the Land Was Won 2.75 Billion Years Ago: New UWAB Research

New research by UWAB student Eva Stüeken suggests that microbes might have been widespread on Earth’s surface around 2.75 billion years ago, where they produced oxygen and weathered pyrite, an iron sulfide mineral, which released sulfur and molybdenum into the oceans. In turn, this sulfur likely enhanced the spread of marine life. To learn more, check out the story in UW News.
